I’d like to build a simple and clean Options page with two upload fields and a preview of the uploaded images. I tried a lot of frameworks like NHP and UpThemes but they are way to heavy for my purpose (e.g. I don’t need several options tabs).

I found this which fits to my needs but I don’t know how to add a second upload field. Any help would be appreciated!

<?php
function wptuts_get_default_options() {
    $options = array(
        'logo' => ''
    );
    return $options;
}


function wptuts_options_init() {
     $wptuts_options = get_option( 'theme_wptuts_options' );

     // Are our options saved in the DB?
     if ( false === $wptuts_options ) {
          // If not, we'll save our default options
          $wptuts_options = wptuts_get_default_options();
          add_option( 'theme_wptuts_options', $wptuts_options );
     } 
     // In other case we don't need to update the DB
}
// Initialize Theme options
add_action( 'after_setup_theme', 'wptuts_options_init' );


function wptuts_options_setup() {
    global $pagenow;
    if ('media-upload.php' == $pagenow || 'async-upload.php' == $pagenow) {
        // Now we'll replace the 'Insert into Post Button inside Thickbox' 
        add_filter( 'gettext', 'replace_thickbox_text' , 1, 2 );
    }
}
add_action( 'admin_init', 'wptuts_options_setup' );


function replace_thickbox_text($translated_text, $text ) {  
    if ( 'Insert into Post' == $text ) {
        $referer = strpos( wp_get_referer(), 'wptuts-settings' );
        if ( $referer != '' ) {
            return __('I want this to be my logo!', 'wptuts' );
        }
    }
    return $translated_text;
}
